The Classic Series™ proves that entry-level optics don’t have to be poor-quality optics. Unlike some other brands, we don’t use the word “value” as a euphemism for “junk”. Classic Series scopes are perfect for the budget-conscious and the new shooter. We take the time to 100% inspect every product in our facility here in Houston to ensure you are receiving the best quality product as our other three tiers. These scopes are backed by the same excellent customer service and support as all other Primary Arms products.

This Primary Arms Microdot sight is our second-generation model that comes in at an affordable price while retaining excellent quality and durability. We have included a MIL-STD-1913 Picatinny rail mount with this red dot sight, so you can attach it to your rifle right out of the box in a matter of seconds and head to the range to get it sighted in. Alternatively, the mount is removable and features mounting options for other standard microdot riser mounts, so you can customize the height and co-witness with your iron sights. Adjusting the zero of the dot is made easy with the 1/2 MOA audible click adjustments that are protected by aluminum caps. Also included with this optic is a bikini lens cover to protect the glass when not in use. If you are in the market for a red dot sight for hunting, target shooting, or competition, you can’t go wrong with the Primary Arms Microdot.

The 2 MOA red dot is extremely crisp and allows you to take quickly aimed shots at short range while still giving you the ability to make effective shots at medium ranges.

The glass and electronic internals are covered by a durable, black hard coat anodized, 6061 aluminum housing with O-rings providing protection from water and fog.

Bargain Micro Dot


Excellent 2 moa red dot for the money. If your needs are for combat, pay the extra money for an Aimpoint. If you want a great quality substitute at a reasonable price then Primary Arms is the way to go. What sets Primary Arms apart is customer service. Anytime I have ever had an issue, it's been addressed and corrected immediately. In fact, I would say Primary Arms encourages feedback to better their products. I find it refreshing to see.

Excellent sight


Excellent little piece of equipment. I've seen several videos of people torture testing these and they hold up incredibly well for a cheap (priced) red dot. I'm positive they're not as solid as an aimpoint T1 micro but they're also nowhere near $600+ either. The brightness is very adjustable for any light condition you will ever encounter.

Awesome red dot


Excellent red dot. Sharp dot, built well, great brightness adjustment, works awesome with my long eye relief magnifier. I shoot around 100yards and it works great. Primary arms, as always, were awesome. Best customer service in the industry.

Primary Arms Micro Dot With Removable Base


Excellent sight for someone on a budget. Will mount on Mid-West Industries AK-47 low mount hand-guard. Hope to be able to co-witness the micro-dot with the iron sights.

Microdot scope

primary arms never let's me down


Fast shipping, great communication and customer service. The micro dot is fantastic. Can't wait to put some on my other toys



For the money, you can't beat these.

NEW!!!! Primary Arms Micro Dot With Removable Base


Good glass clarity as always. The dot gets incredibly fuzzy though at anything but the lowest tolerable setting. Dot all but disappears in bright sunlight unless on highest setting, and the blue tint to the glass throws off 2 eye operation. Overall I'm very happy though, especially for the price an build quality. Great weight, size/form, price point, etc. Very happy once again.
